This invention relates to a winding apparatus,

1 and more particularly to a non-stop automatic transfer windingapparatus. The present application is filed in place of my abandonedapplication Serial No. 470;987.

An object of the invention is to provide a mechanism for continuouslywinding "a web of paper on a plurality of successive cores in acompletelyautomatic operation.

Another object ofz-the invention is to provide;

apparatus for winding a'web on a core or mandrel 'and automaticallysevering the web and transferring the'lea'ding end thereof to anotherfcore or mandrel without interrupting-the winding operation. Stillanother object is to provide a single machine, apparatus for slittingand"perforating a web of paperand for automatically 'severing the webatVpre-determined intervals so that the web may be continuously wound onsuc- --cessive cores.

Another object of the invention is to provide means for automaticallysevering a paper web "which is being woundon a mandreland for urg- 'ingthe leading end of the severed web against "anothermandrel. Stillanotherobject isto provide mechanism for continuously moving a plurality-ofmandrels-and for synchronizing with the movement ofthemandrels; theseverance of the paper web and the bringing of the leading end of thesevered web into engagement with a man-- drel.

Other features and-advantages will appear from the followingspecification and'drawings, in Which:

Inthe embodiment of the invention described herein and as shownmoreclearly inFigs. 1 and 2, apaper web Wis-passed between a drive rollH and a bed roll 12. In passing about the bed "roll I2, the webis-brought intoadjacent relation with a perforating roll -l3andasplitting T011 [4 and then passes between the'bed roll '12 andanother drive roll l5. From the bed roll'jlZ,

the paper-web passes to andis wound upon one wofthe-cores l6, l'l, lB-and lflmouhtedrespec- 1tively on the mandrels :20, 21,22 and '23. Theap- I spaced portions of the web.

to frictionally engage the .web I 0 ftherebetween.

The positively driven rolls I5 and II are rotated The mandrels' 20, 2],.22 and"'23nare,rotata rotatably supported by the shaft 33. The turret32 may bearranged for rotation on thefshajfti fl soas to move themandrels carriedjtherebyifin the counter-clockwise v directionindicated, by the arrowin" Fig. 1. Any suitable mechanism .may

be used for rotating the turret. Preferably; the turret is rotated atsuch a speedthatan'iandrel -22 in web. winding position as "shownin"Fig. l,

may be moved tothe position 'of the mandrelifl, in Fig. .1, in the timerequired to windy'the web to its full extenton the core on'the; mandrel.

Thus,the core on the mandrelreceives,.the web when the mandrel reaches"theiw'eb winding posi-- tion of the mandrel 22 Q shown Figl 1, ,ar'idfgby the time the .web has been completely wound on the core onthemandrel, the mandrel has reached the position beyond web,windingposition-gin which themandrel'l23. is shown inFigi 1'.

An arm 34, which. mayif desiredbemounted on the sh'a'ft 25, carriesal-knifebladei35iand. a nozzle 36. The arm 34 is arranged to movetowardand away fromthe web lfl atjtheportionthereof between themandrelsi22and23fi The knifebl ade .35 may be of. any I suitable orc'onventional -type 3 adapted to sever the web when brought intoengagement therewith. The nozzle 36 is adapted to receive a conduit fordelivering fluid under pressure to the nozzle 36. Preferably, a mixtureof compressed air and water is passed into the nozzle and emittedtherefrom under pressure.

The arm 34 may be actuated by any suitable means so as to bring theknife blade 35 into engagement with the web l8 at the portion thereofbetween the mandrels 22 and 23 to sever the web |8 when the core H! onthe mandrel 23 has been fully wound with the web. Preferably, theactuating means for the arm 34 is automatically operable and issynchronized with the movement of the turret 32 so that the arm 34 ismoved forwardly when the mandrels reach the position shown in Fig. 1.

The fluid, which is supplied to the nozzle 36. is controlled by asuitable valve mechanism so that fluid under pressure is ejected fromthe nozzle 36 immediately after the web l8 has been severed by theaction of the knife 35. The nozzle 36 thus serves to bring the fluidinto engagement with one side of the leading end of the severed web, andthus causes the leading end of the severed web to be brought intoengagement with the core |8 of the mandrel 22, as seen in Fig. 2. Fluidis ejected under pressure from the nozzle 36 only immediately after theseverance of the web l0, the valve mechanism being synchronized so as tooperate only at the periodic intervals of the actuation of the arm 34.

When the web ID has been fully wound on the core IS on the mandrel 23and the mandrel 23 reaches the position shown in Fig. 1, the arm 34 isautomatically actuated to bring the knife 35 into engagement with theweb ID. The knife 35 severs the web at the portion thereof between themandrels 22 and 23. Immediately upon the severance of the web H] by theknife 35, the nozzle 36 ejects a stream of fluid under pressure(preferably a mixture of compressed air and water) to force the leadingend of the severed web into engagement with the mandrel 22. The mandrel22, of course, is in engagement with or immediately adjacent the side ofthe web opposite that which is adjacent the knife blade 35 and nozzle36.

A complete machine, which supplies the power for the various operationsshown in Figs. 1 and 2, is set out more fully in Figs. 3, 4 and 5. Inthe latter figures, A designates a base or frame for supporting theoperating mechanism hereinafter described. A bracket A provides asupport for the roll 40 which carries the paper stock H).

A main drive shaft 25 is mounted in the frame A and is equipped with adrive wheel 4| to which power may be supplied by belt or by gearmechanism or by any suitable means. The drive shaft 25 carries the bedroll l2, and at the opposite end of the casing is equipped with a gear42 meshing with the gear 43 on shaft 24, the gear 44 on shaft 26, thegear 45 on shaft 29, and, as shown more clearly in Fig. 4, the pinion 46on shaft 3|. Shaft 3| carries also the pulley drive member 41.

Suitable pulley and belt means are provided for driving the mandrels 20,2|, 22 and 23 on the turret 32. Such belt mechanism is shown moreclearly in Fig. 3. A pulley 48 is mounted upon a standard 49 carried bycasing A and receives a belt 50 driven by pulley 41.

Pulley 48 is fixed to a rotatable shaft and shaft 5| carries anotherpulley 52. A belt 53 connectsthe pulley 52, a pulley 54 carried by shaft3|, and an idler pulley 55 carried by shaft 56.

Shaft 56 is mounted upon an arm 51 pivotally carried upon casing A byshaft 58 and is urged outwardly against belt 53 by an integrallyweighted arm 58. The belt 53 is adapted to engage a drum 68 carried byeach of the mandrels 20, 2|, 22 and 23 and, as shown best in Fig. 3, thebelt normally engages two of the drums at one time. By this means, therotation of each of the separate mandrels, when in contact with thepaper web I0, is rotated independently of the turret shaft 33.

Power is supplied to the turret shaft 33 by the following means: Theshaft 25 is provided with a worm 6|, as indicated in Fig. 3, and theworm 6| meshes with a worm gear 62 carried by a cross shaft 63. The endsof the cross shaft 63 are provided with bevel gears 64 and 65. Bevelgear 64 meshes with gear 65 carried by shaft 66. Shaft 66 extendsthrough the frame members A and at its opposite end carries gear 61.Gear 61 meshes with an intermediate gear 68 carried upon shaft 69 and,in turn, gear 68 meshes with the upper gear 10 carried upon shaft 1|.Shaft 1| carries a pinion 12 which meshes with the large gear 13 carriedby turret shaft 33.

Power is supplied to the knife 35 and to the fluid discharge member 26by the following means: The bevel gear 65 carried by the cross shaft 63meshes with bevel gear 14 mounted on shaft 15. Shaft 15 carries a wheel16 to which an eccentric member 11 is pivotally mounted by means of pin18. The eccentrically-mounted member 11 carries a rod 18 which pivotallyengages the member 34 carrying knife 35, as shown best in Fig. 3.

Any suitable means for automatically supplying fluid to the nozzlemechanism 26 may be employed. In the illustration given, the nozzles 26are connected by a manifold pipe secured to the knife arm 34.Communicating with the pipe 88 is a flexible hose 8| which is supportedby bracket 82 on casing A. A pipe 83 connects the hose 8| with a valvedevice 84, as shown more clearly in Fig. 3. The valve device 84 isprovided with a plunger 85 adapted to be engaged by a cam 86 carried bythe wheel 16. The cam 86 controls the operation of the plunger 85 torelease fluid in timed relationship with the action of the knife whencutting the paper web I, as heretofore described.

An idler roller 81 is carried by shaft 88 and provides a support for thepaper web I0.

In operation, the web It! is drawn between the drive roll H and the bedroll l2 and is passed along the perforating roll l3 and slitting roll l4and then between the drive roll l5 and bed roll |2. In passing theperforating roll l3 and slitting roll M, the web is perforated and slit.From the drive roll |5, the web continues to pass along the bed roll |2to the core l9 on the mandrel 23. As the turret 32 is rotated and themandrels are moved to the web winding position of mandrel 22 and thenbeyond this position to the position of mandrel 23, the arm 34 isactuated at intervals so as to sever the web I0 at the portion thereofbetween the mandrels 22 and 23. The severing of the web is immediatelyfollowed by the application of fluid pressure to the side of the leadingend of the web which is opposite the side adjacent the mandrel 22. Inthis manner, the web is brought into engagement with the mandrel 22 andis wound thereon. The continued operation of the device brings themandrels 20 and 2| into web winding position and then beyond thisposition. The web is continuously and automatically wound upon the coreson successive mandrels, the transfer of the web from one mandrel toanother being completely automatic.

Although the invention has been described in connection with aparticular embodiment, it will be apparent that modifications andchanges may be made without departing from the spirit and scope of theinvention.
